摘要
根据桃山复式花岗岩体中锆石单形组合特征,把锆石划分三种类型,从锆石形态、结构以及化学成分特征,找出它们之间的差异,发现复式花岗岩体中锆石由老到新的过程中出现两次规律性的变化。
According to zirconite the forms,constitutions and chemical associations the single zirconite in complex granite in the area of Taoshan Mountains can be divided into three types. The differences between them can be found out based on the analytical results. The author shows that there have been two regular changes of zirconite in complex granite in whole the course of its formation.
